Applying a “substituting space for time” approach for northern and southern parts of the river basin, we suggest that the current riverine CO2 emission may increase 2 to 3 fold in the next decades due to on-going climate warming and permafrost thaw. When integrating the obtained results into global models of C and biogeochemical cycle in the Arctic and subarctic region, the use of the Taz River as a representative example of continental planes should help to estimate the consequences of frozen peatland thaw on CO2 cycle in the Arctic and subarctic regions.]]> Thu 09 Nov 2023 09:56:02 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001008912 70% of annual Mn flux occurred in winter. A number of elements present in the snowpack exhibited sizable (> 45%) export during spring flood (Zn, Cu, Pb, Cd, Sb and Cs). The 3 years mean export fluxes (yields) of dissolved components were comparable to or 30–50% lower than those of other large and medium sized Arctic rivers. This was due mostly to a lack of fresh unaltered rocks and a dominance of peatlands within the Taz River watershed. Elevated concentrations of redox-sensitive micro-nutrients (such as Fe and Mn) occurring during winter baseflow can be linked to disproportionally large floodplain zone of this river which can act, especially in the river's lower reaches, as a stratified lake thereby releasing high amounts of redox-sensitive elements from the sediments. The role of suboxic zones in the Arctic boreal riverine landscape may be more important than previously thought, and may allow explaining anomalously high concentrations of some metals (i.e., Mn) reported in Arctic Ocean surface waters. It is anticipated that climate warming in the region may increase the contribution of winter flow and enhance the export of soluble elements and some nutrients (such as Si, Mn and Co).]]> Thu 09 Nov 2023 09:55:57 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000894953 Thu 02 Jun 2022 10:40:31 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001001201 Fri 19 May 2023 10:50:08 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000891432 Fri 01 Apr 2022 10:10:19 KRAT ]]>
